The 12" DUO Kitchen DUO Tongs feature our patented half 500 degree silicone (BPA Free) and half stainless steel heads, which make them safe for all types of cooking surfaces and picking up just about anything. They have a single drain slot in one side and a solid head on the other for scooping sauce. The tong heads are slightly angled for picking up delicate foods easier on the silicone side. The TPR non-slip grip with the spring tension give you full control. The back side features a round loop locking ring which slides out to lock the tong shut or slides in and stays put so your kitchen tongs stay open in all usable positions. The Only Tongs You'll Ever Need!
